NETED STATES PATENT Erica,

WINDOW-SCREEN.

SPECIFICATION forming part of Letters Patent No. 651,097, dated June 5, 1900. Application filed March 10,1899. Serial No. 708,568. (No model.)

To all whom, it may concern.-

Be it known that I, ERNST O. F. EARTH, a subject of the Emperor of Germany, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Window-Screens; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled screen of this character which is adjustable to any window and in which the screen-netting is wound on a spring-actuated roller, somewhat after the fashion of an ordinary window-shade.

The several novel features of construction and combination of parts will hereinafter be more fully described, and defined in the claim appended, reference being had to the accompanying drawings, in which similar numerals designate similar parts in the several views.

Figure 1 is a view of a Window-frame with my improved screen attached thereto and showing the screen-netting partly drawn. Fig. 2 is a detail view of part of the screennetting. Fig. 3 is a cross-section of one of the standards. Fig. 4 is a detail view with a portion of the standard cut away, showing the adjustable bracket.

The window is designated by the numeral 1, in which is fitted the screen. The screen consists of standards 2, secured to the windowframe by any suitable means. In this case I employ a metal brace 12, one end of which is secured to the window-frame and the other to the standard, spring-roller 3, to which is mounted the screen-netting 4:, the same being reinforced by the rod 5. Into the upper end of each standard is adj ustably secured a bracket furnishing a j ournaling for the roller 3. The brackets are each provided with a clamping-bolt 10, which passes through the slot 6 in each standard, and the bracket is clamped by a suitable thumb-piece 11. The standards 2 are each provided with a longitudinal slot 7,which extends the entire length thereof and into which the edge of the screen is adapted to pass. To obtain a more efficient and satisfactory screen, the slot in each standard is furnished with a plurality of grooves 8, which individually are intended to form a passage or path for the reinforcing rope or strip 9 on the screen-11etting. In order to facilitate the rolling of the screen, the strips 9 do not extend the entire length of the same, yet are long enough to possess sufficient bearing in the grooves to hold the screen firmly, so as to prevent displacement by wind, accident, &c.

It is obvious that a window-screen as above described is operated much after the manner of an ordinary window-shade, and in adj usting it to the frame of the window it is necessary first to select the proper groove in the longitudinal slot for the passage of the rope or strip, after which the brackets are adjusted for the roller, and then, finally, the standards are secured to the frame of the window.

I desire to have it understood that such changes as are within the spirit of my invention I still reserve and do not limit myself by the above description.

Having thus described my invention,what I claim as new, and desire to secure by Letters Patent, is

An improved window-screen consisting of two standards, adjustable brackets at the upper ends of the standards, a spring-actuated roller journaled in the brackets, a screen secured to the roller, longitudinal slots in the standards, a plurality of grooves communicating with each slot, strips corresponding to and adapted to fit in said grooves secured to the screen-netting, whereby the netting is securely held in place and guided in operation, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.

ERNST C. F. EARTH.
